PAVEMENT DEFICIENCIES RELATED TO ASPHALT DURABILITY

This paper provides an overview of the focus of the Symposium entitled, "Asphalt Durability: Source and In-Service Effects," held at the Asphalt Paving Technology 1981 Technical Sessions. The Symposium was directed, specifically, to a deliberation of how the performance of an asphalt, with respect to its durability in an asphalt/aggregate paving mixture, is affected: 1) by where it comes from, both with respect to crude source and refining method; and 2) by how it responds to the in-service conditions of both environment and traffic.
